LINER FOR CENTRIFUGAL SEPARATORS.

SPECIFICATION forming part of Letters Patent No. 788,1 16, dated April25, 1905.

Application filed June 16, 1904. Serial No. 212,857.

To all whom it may concern:

Be it known that I, ERIK NYLEN, a subject of the King of Sweden andNorway, and a resident of Stocksund, Sweden, have invented new anduseful Improvements in Liners for Centrifugal Separators, of which thefollowing is a specification, reference being bad to the drawingaccompanying and forming a part hereof.

This invention relates to improvements in liners for centrifugalseparators.

The object of the invention is to subject the milk or the other liquidto be separated to a preliminary treatment which will facilitate theusual separation process.

The invention consists in the combination, with a centrifugal-separatorbowl having discharging devices for the blue milk and the cream, of acentral inlet-pipe, a funnel-shaped portion on the latter provided witha number of holes and dividing the bowl in an upper and a lower chamber,a liner in the said upper chamber, and a funnel in the said lowerchamber dividing the latter in two parts. By this device the full milkwill be sub ected to the centrifugal force during a comparatively longtime before entering the liner, and trials have proved that suchpreliminary treatment of the full milk is very favorable for theseparation and accelerates the same.

In the accompanying drawing I have shown a liner embodying my invention.

The figure shows a vertical section of a centrifugal-separator bowl anda liner constructed in accordance with the present invention.

Referring to the drawing, the central inlet-pipe I is at the lower endprovided with a funnel-shaped portion 2, dividing the bowl 3 in twochambers at and 5, the upper of which constitutes the usualseparation-space and is provided with a liner 6, consisting in wellknown manner of conical ring-shaped plates superposed on one another.The said funnelshaped portion tightens against an inwardlyprojectingflange 1% on the bottom 8 of the bowl. In the lower chamber 5 isprovided a funnel 13, dividing the said chamber in two parts. Thefunnel-shaped portion of the central inlet-pipe 1 is provided withopenings 15, through which the full milk will rise along flanges 11 onthe central inlet-pipe. The said holes may preferably be arranged insuch radial distance from the center of the bowl as to lead out the fullmilk outside the wall of cream obtained in the separation process inorder not to disturb the said wall of cream.

The devices now described work as follows: The full milk led into thecentral inlet-pipe will be thrown out into the space between the funnel13 and the bottom 8 of the bowl and will thereupon, inasmuch as thefunnel-shaped portion 2 of the central inlet-pipe tightens against theinwardly-projecting flange 14 on the bottom 8, flow inward between thesaid funnel l3 and the funnel-shaped portion 2 of the centralinlet-pipe, whereupon the milk will rise through the holes 15 and enterthe liner, in which it will be separated in the usual manner. The bluemilk will leave the bowl through tubes 9, while the cream will Fe thrownout through the usual cream-out- Having now described my invention andin what manner the same may be performed, what I claim as new, anddesire to secure by Letters Patent, is-

The combination with a centrifugal-separator bowl having dischargingdevices for the blue milk and the cream, of a central inletpipe, afunnel-shaped portion on the latter provided with a number of holes anddividing the bowl in an upper and a lower chamber, a liner in the saidupper chamber, and a funnel in the said lower chamber dividing thelatter in two parts, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ERIK NYLEN.
